CREANFTESTNG CHURN.

SPECIFICATION forming part of Letters Patent No. 392,865, dated November13, 1889e Application filed March 23,1888. Serial No. 208,241. (Nomodel.)

To @ZZ whom it may concern:

Be it known that I, BYRON KANABLE, of Marion. in the county of Marionand State of Ohio, have invented certain new and useful Improvements inCream-Testing Ghurns; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to an improvement inV creau1-testing7 churns.

The object of my present invention is to provide a simple, light, andconvenient device which may readily be transported from place to place,and furnish a convenient means for quickly churning a sample of creamtaken from a cream-venders pail, preferably at the residence of thecream-producer.

Vith these objects in view my invention consistsiu certain features ofconstruction and combinations of parts, that will be hereinafterdescribed, and pointed out in the claims.

The device which is the subject of this invention is one of theessential mechanical features preferably employed to carry into effect anovel process invented by me and which is the subject of another patent.The process alluded to is an improved method of determining accuratelyaud speedily the amount of butyric oil contained in a sample of cream,so as to ascertain by its proportionate volume the commercial value as abutter-making material of a body of cream contained in a vessel fromwhich the sample was extracted.

Referring to the drawings making a part of this specification, Figure 1is a side elevation ofthe cream-testing churn, with a test-tube thatholds the cream in place on the churn to be agitated by the action ofthe churn. Fig. 2 is an end elevation of the churning device.

The frame E of the cream-testing churn cousists of an upright metalbracket which has two limbs, E', formed integral with the upper portion,these limbs being curved away from each other and made parallel, soas'to afford a light and Vstiff column, that is attached to orintegrally formed upon the top face of the baseplate EZwhich is ofsufficient area to properly support the entire mechanism.

, On the upper end of the frame E a horizon` tal cylindrical hub, E3, isformed,which is perforated axially to receive a shaft, m. In order totake up any lostmction which may result from a rapid motionl of theshaft in the supporting-box E3, the latter is longitudinally and axiallyslotted, as well as the upper portion of the frame E, as shown atf inFig. 1, and asetbolt, g, is inserted to clamp the separate portionstoward each other.

Upon the right side of the frame E a cylindrical stud, C2, is made toproj ect,which is held in place by its integral collar K, bearing on oneside of the frame'and clamped thereto by a nut, C', which engages theother side surface of the frame, as shown in dotted lines in Fig. 2. Thestud O2 is intended to revolubly support the spur gear-wheel F, thehub Cof which is perforated to engage this stud and is held in place by awasher, w, and pinp, as shown in Fig. 2. On the wheel F a crank-handle,O, is attached to afford means for the revolution of the wheel andoperation of attached parts.

Upon a projecting end of the shaft m a small pinion, F', issecured,which is of a proper diameter to mesh with the spur-wheel F, andon the opposite extended end of this shaft m a crank-disk, G, isaffixed, which latter is perforated at a proper point to receive thecrankpin h. (Shown in dotted lines in Fig. 2.)

A spring-bar, H, which is made of elastic material, either wood ormetal, is attached to the base-plate E by secured engagement of itslower end with a projecting lug, lo, that rises from the base-plate at aproper point. The length of the spring-bar H is proportioned to theheight of the frame E, so that its upper end will extend above the frameto clear it, and on this upper end two clamping-jaws, P P, are

formed,which are elastic and have a tendency to spring apart whenunchecked.

The upper extremities, P', of the jaws P are curved to produce clamps,which together are adapted to embrace the cylindrical body of atest-tube, D, as shown in Fig. l; and to retain the tube in place withinthe clamping-jaws P a cross-bolt, o, and its nuto are made to engage thetwo jaws on their outer surfaces by insertion of the bolt throughperforations made in the jaws P, as shown in Fig. 2. The crankpin 7L ofthe disk G is inserted through a lon- IOO gitudinal slot, h, (see Fig.1,) and is held in sliding contact therein by a plate, h', and cross pint.

From the foregoing description of parts of this churning device it willbe apparent that a revolution of the spur-wheel F will rapidlyreciprocate the upper end of the spring-bar H and an attached test-tube,D, and, as this tube is adapted to receive a certain quantity of creamand retain it, the vibration of the tube, when it is charged with cream,will rapidly change the cream into butter and buttermilk by thepercussive action of the machine, this being the function of the deviceherein described.

I do not desire to limit the construction of this cream-testing churn tothe exact forms herein shown, as it is evident that the same may beslightly varied without a departure from the spirit of my invention.Neither do I Wish to limit myself to the clamped support andchurn-agitation of a single test-tube at one time, as it is readily seenthat there may be two or more clamps affixed to the top of thespring-bar H to receive and reciprocate at the same time more than onetube, and thus churn the contents of two or more test-tubes by oneoperation, if it is desired.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a cream-testing churn, the combination,with a frame carryinggearing, of a springbar rigidly secured to the frame at one end andprovided at its free end with jaws for clamping a churn, the said barbeing connected to the gearing at a point between its ends,substantially as set forth.

2. In a cream-testing churn, the combination, with a base-plate, aframe, and gearing supported to revolve on this frame and adapted tovibrate a spring-bar, of a spring-bar and clamping-jaws formed on thisspring-bar, substantially as set forth.

8. In a cream-testing churn, the combination, with a frame, abase-plate, a spur gear- Wheel, a pinion, a shaft, and a crank-disk, ofa vertical slotted spring-bar, clamping-jaws for this spring-bar, and ameans of rotating the gearing to vibrate the sp ring-bar, substantiallyas set forth.

In testimony whereof I have signed this specification in the presence oftwo subscribing` witnesses.

BYRON KANABLE.
